I have just had my 1.9 cdti sport-hatch for a service at my local Vauxhall dealer and i have been told that the front flexi pipe needs to be replaced on the exhaust and to do this they say that the front section needs to be replaced, (apparently something to do with the CAT). The cost of this will be £495 for the parts and to fit it will be a total cost of £707.

Has anyone else had this problem and does anyone know if i could fit either a aftermarket flexi pipe thingy the front section or a full exhaust ???
